Solve the radical equation. x+1=7-6x-6
Which solution is extraneous?
The solution x=-1 is an extraneous solution.
Both x=-1 are x=-7 true solutions.
O The solution x=-7 is an extraneous solution.
O Neither x=-1 nor x=-7 is a true solution to the equation.

the answer is here: : )

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
